@s2quake s2quake commented Apr 8, 2024

Features

  • Slashing -> SlashCtrl.Shash
  • Jailing -> ValidatorCtrl.Jail
  • Unjailing -> ValidatorCtrl.Unjail
  • Tombstone -> ValidatorCtrl.Tombstone
  • Penalties for double signing -> EvidenceCtrl

Test Codes

  • SlashCtrlTest: Unit and senario test
  • ValidatorSigningInfoCtrlTest: Unit test

References

  • There is code(from cosmos) for infraction due to network latency, but it has not been tested.
  • The code for the case where the slash factor is 100% is not implemented.
  • The test code for the case where there is a remainder when dividing by a slash factor is not implemented.
  • Very complex test code like delegate->redelegate->adelegate is not implemented.

This PR has 1818 quantified lines of changes. In general, a change size of upto 200 lines is ideal for the best PR experience!

Why proper sizing of changes matters

Optimal pull request sizes drive a better predictable PR flow as they strike a
balance between between PR complexity and PR review overhead. PRs within the
optimal size (typical small, or medium sized PRs) mean:

  • Fast and predictable releases to production:
    • Optimal size changes are more likely to be reviewed faster with fewer
      iterations.
    • Similarity in low PR complexity drives similar review times.
  • Review quality is likely higher as complexity is lower:
    • Bugs are more likely to be detected.
    • Code inconsistencies are more likely to be detected.
  • Knowledge sharing is improved within the participants:
    • Small portions can be assimilated better.
  • Better engineering practices are exercised:
    • Solving big problems by dividing them in well contained, smaller problems.
    • Exercising separation of concerns within the code changes.

What can I do to optimize my changes

  • Use the PullRequestQuantifier to quantify your PR accurately
    • Create a context profile for your repo using the context generator
    • Exclude files that are not necessary to be reviewed or do not increase the review complexity. Example: Autogenerated code, docs, project IDE setting files, binaries, etc. Check out the Excluded section from your prquantifier.yaml context profile.
    • Understand your typical change complexity, drive towards the desired complexity by adjusting the label mapping in your prquantifier.yaml context profile.
    • Only use the labels that matter to you, see context specification to customize your prquantifier.yaml context profile.
  • Change your engineering behaviors
    • For PRs that fall outside of the desired spectrum, review the details and check if:
      • Your PR could be split in smaller, self-contained PRs instead
      • Your PR only solves one particular issue. (For example, don't refactor and code new features in the same PR).

How to interpret the change counts in git diff output

  • One line was added: +1 -0
  • One line was deleted: +0 -1
  • One line was modified: +1 -1 (git diff doesn't know about modified, it will
    interpret that line like one addition plus one deletion)
  • Change percentiles: Change characteristics (addition, deletion, modification)
    of this PR in relation to all other PRs within the repository.
